New to Site...question about engine code on 2000 Protege ES?
Hi...I'm new to the site...My GF has a 2000 Protege ES.
Her check engine light was on a few months back and we had it read...came up with 3 codes, 1 small exhaust leak, 1 larger leak, and a 3rd code that i cant remember...
her large leak was cause her airbox had a broken clip, i fixed it and we had the light reset...
it came back on a day later...we just had it read and the mechanic said it was Code P1114 or P114...Warm Up Improper? he advised that she let the engine run 5-10 minutes each time before driving...
today, she was in a rush and only let it run for about 1-2 minutes...outside temp was about 70+, car had just made a 20 mile commute with no light...she got out of class and left, thats when it came back on...
Mechanic thinks it has something to do with the Remote Starter that i put in her car, but I HIGHLY HIGHLY doubt it as I have installed these things to many cars and have not had any issues...
any suggestions from the experts here???
thanks...

Hi Mario.
Do you have any other information on the code numbers? Very critical that we know the exact code that has been set as there are a little over 100 different ones that could be set for the 2000 Protege. I assume that she has the 2.0l engine as it is an ES but double check. There are not any codes for exhaust leaks but there are several for EVAP system large and small leaks. There is also no code #'s P1114 or P114. All codes for engine/trans should start with letter P and then followed by four numbers. There is a P1141 that indicates a possible fault in the downstream O2 sensor heater. P0420 or P0421 would point to a front warm-up catalytic converter efficiency below limit. If you could have the code number rechecked at an Autozone and post back up could probably be of much better assistance in what it could mean

Only very rarely would a faulty rear O2 sensor cause a P0421 Cat Efficiency. If the rear O2 was not operating correctly it would more likely set a P0138 or P0140. A non OE converter could be used but would need to be fairly model specific as the bolt pattern of inlet and outlet as well as length would need to match OE part. Is not like a main CAT that you can cut out and weld a new one in. This one bolts right onto the outlet of the exhaust manifold.
